Prevention Coordinators are the linking agents providing technical assistance between universities and communities in the PROSPER model to support the implementation and sustainability of youth and family programs that have reduced substance abuse in prior research. This study examines the outcomes and trajectory of the frequency of contact of technical assistance (i.e. dosage) with community collaborative prevention coalitions across the three stages of coalition development. After communities were randomized, members of PROSPER coalitions (n=12) provided information about the quality of their operations at five time points across four and one-half years; prevention coordinators reported on the frequency of contact with their community coalitions at 14 intervals across the same period of time. This study only utilizes the intervention communities. Results from correlational models show that levels of dosage relate to the quality of internal coalition processes over time, but that the direction of the relationship changes over time: high frequency of contact early on relates to lower coalition-rated functioning initially. In contrast, early frequency of contact relates to higher levels of coalition functioning at later time points. Furthermore, longitudinal mixed models show that levels of dosage were consistent over time. These results provide empirical support of the importance of a proactive technical assistance model and add further evidence that important distinctions exist among different coalition developmental phases.
预防协调员是在“繁荣”模式下为大学和社区之间提供技术援助的联络人，以支持那些在先前研究中减少了药物滥用的青年和家庭项目的实施与可持续性。本研究考察了在联盟发展的三个阶段中，技术援助（即剂量）与社区合作预防联盟的接触频率的结果和轨迹。在社区被随机分组后，“繁荣”联盟的成员（n = 12）在四年半的时间里的五个时间点提供了有关其运作质量的信息；预防协调员在同一时期的14个时间间隔报告了与社区联盟的接触频率。本研究仅使用干预社区。相关模型的结果表明，随着时间的推移，剂量水平与联盟内部流程的质量相关，但这种关系的方向随时间而变化：早期的高接触频率最初与联盟评级的较低运作水平相关。相比之下，早期的接触频率在后期时间点与联盟的较高运作水平相关。此外，纵向混合模型表明，剂量水平随时间保持一致。这些结果为积极主动的技术援助模式的重要性提供了实证支持，并进一步证明了不同联盟发展阶段之间存在重要差异。
